Nyob rau hauv cov kev tshwm sim uas cov acoustics tau muas nyob rau hauv ib tug siv thiab tam sim no zoo hnav los ntawm lub neej, nws yog tsim nyog los txuas qhov tseem ceeb rau lub ntsej muag. Ua li no, koj yuav tsum disassemble tus hais lus S90, tom qab muab tso rau ntawm "rov qab".
Thaum tshem tawm cov neeg hais lus, thov nco ntsoov tias lub taub hau treble thiab nruab nrab yog txuas rau rooj plaub uas siv tib lub ntswj raws li cov nets thiab trims. Lub woofer txuas nrog nyias, thiab koj yuav tsum tau ceev faj kom tsis txhob ua kom nws puas thaum unscrewing.
Tom ntej no, koj yuav tsum rub tawm cov theem inverter, tom qab tshem lub hau ntawm nws. Txij li qhov ib feem yog yas, nws tsim nyog thov kev saib xyuas siab tshaj plaws kom tsis txhob cuam tshuam cov fasteners.
Cov treble / nruab nrab tswj tau yooj yim dua tshem tawm ntau dua li qhov koj xav. Txhua yam koj yuav tsum tau ua yog ua tib zoo tshem tawm cov kaus mom zoo nkauj uas nyob hauv nruab nrab ntawm txhua pob qhov rooj. Tom qab ntawd, siv lub hau ntswj, nws yog ib qho tsim nyog yuav tsum tau unscrew lub hau ntswj uas tau qhib rau lub qhov muag, thiab tshem tawm cov regulator knob nws tus kheej. Cov yas hauv ob sab phlu yuav tsum tau ua tib zoo nqa los ntawm ob sab nrog kev pab los ntawm cov khoom tiaj tus thiab tshem tawm, thiab plaub lub screws uas tseem tshuav nyob rau hauv nws yuav tsum tau unscrewed. Tom qab ntawd, lub attenuator tuaj yeem raug thawb rau sab hauv S90 kem, nco ntsoov kom tshem tawm nws los ntawm lim.
Cov hnab paj rwb hauv rooj plaub yuav tsum tau muab tshem tawm. Ib zaug ntxiv, yog tias yav dhau los tus tswv ntawm cov neeg hais lus tsis txhob hnov qab rov qab mus rau lawv qhov chaw nyob rau hauv rooj plaub ntawm kev sib cais.
Koj yuav tsum xub tshem tawm lub vaj huam sib luag nrog cov ntxaij lim dej los ntawm cov zis los ntawm sab nraum qab ntawm tus neeg hais lus, tom qab ntawd nws yuav tsum tau muab tshem tawm los ntawm unscrewing lub screws. Tam sim no koj tuaj yeem tshem lub vaj huam sib luag nrog cov terminals txuas rau nws.
Zoo thiab lub cev
Yog hais tias tus hais lus grilles thiab cov hniav zoo nkauj yog "nkig", ces nws tsim nyog ncaj thiab pleev xim rau lawv, ua ntej xuab zeb thiab degreasing lawv. Qhov no yuav ua rau pom tshiab rau cov neeg hais lus. Lub cev ntawm S90 yuav xoob lub sijhawm thiab tuaj yeem ntxiv dag zog raws li qhov xav tau. Qhov no yuav ua rau lub suab nrov zoo dua.
Qhov no tuaj yeem ua tau ntau txoj hauv kev, suav nrog kev txhim kho spacers thiab ntxiv cov ces kaum sab hauv.

Terminals thiab filter
Paub xov tooj cua amateurs tau qhia kom hloov cov qauv terminals rau kev sib txuas acoustics rau terminals ntawm ib hom universal nrog kub-plated connectors. Lub installation qhov chaw yuav tsum tau lubricated nrog sealant thiab muab lub vaj huam sib luag nrog terminals nyob rau hauv qhov chaw.
Kev saib xyuas yuav tsum tau them rau lub suab lim. Yog tias nws tau txuas nrog lub cev nrog cov ntsia hlau hlau, ces qhov chaw lim dej yuav mus yuam kev. Muaj cov rooj plaub thaum lub lim tau sib sau ua ke ntawm lub phaj hlau. Qhov no yuav tsum tau kho los ntawm kev hloov tag nrho cov nodes mus rau lub vaj huam sib luag plywood. Lub tswv yim ntawm lub lim nws tus kheej tuaj yeem hloov pauv ntawm lub Hoobkas -Chaw tsim tshuaj paus vim muaj qhov sib txawv ntawm cov neeg hais lus, yog li koj yuav tsum xyuas kom meej tias txhua yam tau sib sau ua ke raws li GOST. Yog tias muaj cov jumpers hauv lub lim, ces lawv yuav tsum tau muab tshem tawm thiab hloov pauv, piv txwv li, nrog rau cov hlau tsis muaj pa oxygen nrog ib ntu ntawm 4 hli 2. Nws yog tsim nyog tshem tawm lub attenuator ntawm lub voj voog, vim nws tsuas yog distors lub suab, thiab hloov cov xov hlau uas siv los txuas cov neeg hais lus rau lub lim.
Rau woofers, ib lub xaim nrog hla ntu ntawm 4 mm 2, rau cov neeg hais lus nruab nrab - nrog thaj tsam ntawm 2.5 mm 2, rau cov tweeters yog 2 hli square2. Tom qab ua qhov yooj yim li no, lub lim yuav tsum tau xa rov qab mus rau nws qhov chaw thiab kaw nrog npuas roj hmab.
hais lus thiab lwm yam "me me"
Txiav tawm cov ntsaws ruaj ruaj tshiab rau cov neeg hais lus. Qhov no tuaj yeem ua tau nrog kev pab ntawm pheej yig lossis tsuas yog siv cov nas khawm uas siv tsis tau. Qhov no yog qhov kev xaiv yooj yim tshaj plaws. Tom qab ntawd, koj yuav tsum rov qab mus rau lawv lub rooj zaum thiab muab cov hniav zoo nkauj thiab cov nets.
Ua ntej txhim kho cov tswj hwm, koj yuav tsum tau muab tag nrho cov kev tawm tsam tawm ntawm lawv. Thaum txhim kho lawv nyob rau hauv qhov chaw, nws yog tsim nyog los thov sealant, raws li thaum txhim kho ib theem inverter.
Los ntawm cov kev siv yooj yim no, cov neeg hais lus S90 tau txais lub neej tshiab. Lub suab zoo dhau los ua qhov kev txiav txim siab dua, txawm tias tus nqi me me. Raws li qhov tshwm sim, peb tuaj yeem hais tias yog tias tsis muaj nyiaj rau kim 2.0 hom acoustics, koj tuaj yeem siv qhov kev xaiv no thiab dhau los ua tus tswv zoo siab ntawm lub sijhawm kuaj xov tooj cua Engineering S90. Yog nws tshwm sim li ntawdtsuas yog ib nrab ntawm cov neeg hais lus muaj, tsis txhob chim. Tom qab tag nrho, nws tseem ceeb heev uas S90 kem, ib daim duab uas tuaj yeem pom ntawm yuav luag txhua lub vev xaib ntawm cov neeg nyiam suab paj nruag los ntawm lub sijhawm ntawm USSR, tuaj yeem ua haujlwm ib leeg thiab muab cov txiaj ntsig zoo.
